SFP+ DAC Twinax Cable 2-Meter(6.5ft), 10G SFP+ to SFP+ Direct Attach Copper Patch Passive Cable for Cisco SFP-H10GB-CU2M, Ubiquiti UniFi UC-DAC-SFP+, TP-Link, Netgear, D-Link, Zyxel,Mikrotik and More

Works fine with Mikrotik CRS354-48P-4S+2Q+ and CRS2004-16G-2S+ reporting 10G baseCR

Bought these to connect some TP-Link SX3008F switches to each other, the DACs worked without issues so can't complain!

Half a metre is useless, get the longer lengths.

I got this to attach my server and my main PC to get 10Gb Ethernet. The cable is fantastic quality, certainly seems it'll take a bit of a beating in my rackmount case. Very little else to say, other than highly recommended.

I bought one of these to link my Ubiquiti UDM Pro to a USW-16-POE Gen2 switch mounted directly above it. I fixed the speed of the SFP ports on both devices to 1Gbps (not sure if this was actually necessary) and plugged in this DAC cable. Works perfectly and saves an RJ45 port on both devices for the link.Flushed with the success of this, I bought a second DAC cable to link the UDM Pro WAN2 port to the other SFP port on the same switch, with the port at that end configured to be on a VLAN carrying my secondary ISP connection. Unfortunately this didn't go so well - The USW recognised the DAC but the UDM just showed the SFP as 'unidentified'. Swapping the cables round proved that the new cable was fine and the issue is with the UDM...In summary, a well priced assembly that performs well for its intended purpose.

Created an entire Ubiquiti rack and bought some of their 10GbE DAC cables, however Ubiquiti only have 0.5m length cables.My USW-Pro-24-PoE switch has its 10GbE ports at the front whilst my UNVR has its 10GbE ports at the back, tis meant that Ubiquiti's own cables cannot and will not reach.Got this instead as its longer, and it works flawlessly, Unifi software did not need setting changed or adapted to it. It worked straight off the bat. Its all you want in a cable really.It has been used for the past 4 months now between my Switch and UNVR with 6 cameras sending their live feed through it.

Quality looked and felt very good, unfortunately for whatever reason it kept dropping link between 2 mikrotik routers.I replaced with a generic Fibre cable and that worked immediately.

I bought this to link my Mikrotik RB5009 router and CSS326 switch. Seems to do the job fine, and can't complain for the price. Worked out of the box and synced at 10G, but if I was actually consistently pulling 10G rather than "a bit more than gigabit" I don't know how well it would hold up at this price point.The 25cm version is very short but true to the item description its fine for a 1U distance - as long as your SFP ports aren't too far away from each other! Much tidier in my rack than a coiled up cable. Bit hard to remove - you'll have to use the included pull tab and a bit of elbow grease!
